Objectives: This study examined the association of the total diet quality with the incidence risk of metabolic syndrome constituents and metabolic syndrome among Korean adults. Methods: Based on a community-based cohort of the Korean Genome and Epidemiology Study (KoGES) from 2001 to 2014, data from a total of 5,549 subjects (2,805 men & 2,744 women) aged 40~69 years at the baseline with a total follow-up period of 38,166 person-years were analyzed. The criteria of the National Cholesterol Education Program Adult Treatment Panel was employed to define metabolic syndrome. The total diet quality was estimated using the Korean Healthy Eating Index (KHEI). Hazard ratios (HR) and 95% confidence intervals (CI) for risk of metabolic syndrome constituents and metabolic syndrome in relation to KHEI quintile groups was calculated by multivariate Cox proportional hazards regression model. Results: After adjusting for age, energy intake, income, education, physical activity, smoking, and drinking, the incidence of abdominal obesity and high blood pressure was significantly lower, by approximately 29.7% (P < 0.01) and 25.2% (P < 0.01), respectively, in the fifth KHEI quintile compared to the first quintile in men. A significant decreasing trend of the metabolic syndrome incidence was observed across the improving levels of KHEI (HRq5vs.q1: 0.775, 95% CIq5vs.q1: 0.619~0.971, P for trend < 0.01). In women, the incidence of abdominal obesity and metabolic syndrome was significantly lower, by approximately 29.8% (P < 0.01) and 22.5% (P < 0.05), respectively, in the fifth KHEI quintile compared to the first quintile adjusting for multiple covariates. On the other hand, the linear trend of metabolic syndrome risk across the KHEI levels did not reach the significance level. Conclusions: A better diet quality can prevent future metabolic syndrome and its certain risk factors among Korean men and women.

This study was conducted to evaluate the optimum dietary lipid level in juvenile river puffer. Five semi-purified diets were formulated with corn oil to contain graded levels of lipid levels of 6, 9, 12, 15 and 18%. Fish averaging $8.32{\pm}0.02$ g randomly were fed the experimental diets in triplicate groups for 8 weeks. After the 8-weeks feeding trial, weight gain and specific growth rate of fish fed the 9% diet were significantly higher than those of fish fed the 15 and 18% diets (P<0.05) but there was not significantly different from that of fish fed the 6, 9 and 12% diets. Feed efficiency and protein efficiency ratio of fish fed the 6, 9 and 12% diets were significantly higher than those of fish fed the 18% diet (P<0.05). Visceralsomatic index of fish fed 18% diet was significantly higher than that of fish fed the 6% diet (P <0.05) but there was not significantly different from that of fish fed the 9, 12, 15 and 18% diets. No significant differences were observed in condition factor, hepatosomatic index and whole body composition among all the fish groups. Serum cholesterol and triglyceride fish fed of 18% diet were significantly higher than that of fish fed the other diets (P<0.05). Optimum dietary lipid levels by using broken-line model and by using second order polynomial were estimated at 7.01% and 8.98% for the maximum growth of fish respectively. Therefore, these results suggested that the optimum dietary lipid level could be greater than 7.01% but less than 8.98% for the maximum growth in juvenile river puffer.

The diet composition of juvenile Trachurus japonicus were studied using 195 specimens collected from 2013 (May, June, July, and September) to 2014 (May, June, and July) in the coastal waters of Geumodo, Yeosu, Korea. The size of juvenile T. japonicus ranged from 4.3 to 15.2 cm in body length (BL). Juvenile T. japonicus was carnivorous and crustaceans predators that consumes mainly consumed copepods. Its diet also included small quantities of decapods, cirripedians, nematods, chaetognathans, fishes, amphipods, cumaceans, ostracods and euphausiids. The graphical method for feeding strategy revealed that juvenile T. japonicus is an opportunistic and specialized predator on copepods, especially Corycaeus. affinis, and showed narrow niche width. Juvenile T. japonicus showed ontogenetic diet change. Small size group individuals (4.3-8.0 cm BL) mainly consumed copepods. The portion of this prey item decreased in the large size group (8.0-15.2 cm BL), and this decrease was paralleled with increased consumption of decapods.

[Purpose] The purpose of this study was to determine whether different types of carbohydrate diets with or without exercise changes energy metabolism at rest and during exercise. [Methods] To minimize differences in food and energy intake between experimental groups, mice were pairfed. After 1 week of adaptation, 40 male ICR mice (6 weeks old) were randomly divided into four groups: Sta. (high fat + high starch), Scu. (high fat + high sucrose), StaEX. (high fat + high starch + exercise), and SucEX. (high fat + high sucrose + exercise). StaEX. and ScuEX. groups underwent training by running on a treadmill five times a week. After 10 weeks of training, energy metabolism was measured for 24 h and during a 1 h exercise period. [Results] The final body weight showed no significant difference between the groups. However, the weight of abdominal tissues (epididymal, perirenal, and mesenteric adipose tissue) in training groups was markedly decreased following 10 weeks of training. Results of all energy metabolism (24 h at rest and during 1 h of exercise) showed no significant interactions between diet and exercise. A brief summary of the results of the energy metabolism is that the metabolism related indicators over 24 h were more affected by the dietary pattern than the exercise but during the 1 h of exercise, training had more effect on energy metabolism than diet. [Conclusion] Our findings confirm that: (a) the type of carbohydrates included in the diet influence the metabolic responses over 24 h, (b) training had more effect on energy metabolism than diet during 1 h of exercise, (c) both results; abdominal adipose tissue weight and fat oxidation during exercise are suggestive for a beneficial effect of moderate physical activity on weight maintenance.

This study was carried out to develop nutrition education materials for nutrient intake and the prevention of disease for the elderly and to test their effects on the health-related matters and nutrition intakes after nutrition education. The mean age of the subjects was 71.6 years old. Diet adjustment for health increased a little bit from 2.2% to 11.1% after education but with no significance. The highest reported chronic illness was hypertension. The drinking of the subjects decreased a little bit after their education but wasn't significant. There were no significant changes to the frequency of food consumption across all the items after education, but there was a small increase to the daily intake of milk and dairy products and fruits and to a balanced diet three times per day. There was a significant increase in the intake of such nutrients as energy(p<0.05), protein(p<0.01), lipid(p<0.05), phosphorus(p<0.05), sodium (p<0.05), vitamin $B_2$(p<0.05), vitamin $B_6$(p<0.05), and niacin(p<0.001) after education. Those findings show that nutrition education provided to the elderly had no clear effects on the items that required memorization such as nutrition knowledge but did have some effects on dietary life. If the nutrition education requiring memorization is provided repeatedly with data supplemented, more effective nutrition management will be possible.

Objectives: The purpose of this study was to provide a basic data of nutrition services in home health care by analyzing hospital-based home-visit nutrition education needs of patients at discharge. Methods: Data was collected from September 11 to October 12, 2012 by administering questionnaires to 289 chronic disease patients to be discharged from a university hospital in Pusan. The home-visit nutrition education instruments used for collecting data were developed by the researcher. Results: Regarding the demands of home-visit nutrition education, 62.3% of subjects were willing to use home-visit nutrition education and 37.7% weren't. The main reason for using the home-visit nutrition education was "the effective nutrient management in consultation with an individual's doctor", 38.9% and 31.2% of patients who did not wish to use the service gave the reason for their decision as, "Just by managing the nutritional requirements of a family's diet and, the patient will be able to fully recover", respectively. As for the demand, classified with the areas of home-visit nutrition education, the demand for the area of basic nutrition (3.75/5.00) was the highest followed by, the area of educational nutrition (3.74/5.00), therapeutic nutrition (3.67/5.00), and dietary nutrition (3.55/5.00). The demand for the area of educational nutrition was high "Considering the state of dietary management, such as disease status and drugs", 73.7%. As for the relation between the characteristics of the study subjects and analysis of demand home-visit nutrition education, the characteristic of subjects, that is, "regular home-visit nutrition education", "practice of diet therapy after discharge" had a significant difference statistically (p < 0.01). As for the relation between the needs for fundamental home-visit nutrition education and the demand of home-visit nutrition education, basic nutrition, educational nutrition, therapeutic nutrition, and dietary nutrition had a significant difference statistically (p < 0.01).

Obesity is an independent risk factor fur coronary artery disease in the postmenopausal women, which may be mediated by alteration of blood lipid metabolism. We are aimed to evaluate the effects of low energy diet, restriction of high fat foods and exercise education on weight, fat mass and blood lipid profile. Fifteen postmenopausal obese women were studied. Subjects received detailed advice about how to achieve a reduction of weight by a low-energy diet (1,200kcal), restriction of high fat food and increased exercise in every 4 wks during 8 wk. To evaluate the effectiveness for education programs, dietary fat habit and daily nutrient intakes, exercise were tested before and after intervention. Anthropometry, computerized tomography, and blood lipid profile were assessed before and after intervention. According to the nutrition education, energy intake (from 1776.1 ${\pm}$ 28.2 kcal to 1268.7 ${\pm}$ 115.2 kcal, p < 0.001) and percent of energy from fat (21.9%, p < 0.01) were significantly decreased. However, the index of nutritional quality was over 1.0. On the contrary, exercise (from 341.3 ${\pm}$ 222.1 kcal to 569.4 ${\pm}$ 309.8 kcal, p < 0.05) was increased and dietary fat habit scores (from 30.8 ${\pm}$ 5.2 to 36.1 ${\pm}$ 3.0, p < 0.01) were improved. Also, body weight (4.2%, p < 0.001), BMI (4.5%, p < 0.001), body fat mass (3.4%, p < 0.05) and waist to hip ratio (1.1%, p < 0.05) were decreased. Among abdominal fat, visceral fat (26.1%, p < 0.05) and subcutaneous fat (14.8%, p < 0.01) were decreased. But there was no difference in visceral fat to subcutaneous fat ratio. We observed HDL-cholesterol increase (11.7%, p < 0.05), triglyceride reduction(14.8%, p < 0.05) and atherogenic index improvement (from 2.7 ${\pm}$ 0.7 to 2.3 ${\pm}$ 0.7, p < 0.05) However, there was no change in LDL-cholesterol and total cholesterol. Theses results showed that low energy diet, restriction of high fat foods and exercise education could result in reduction of body weight, fat mass, visceral and subcutaneous fat, and in improvement of blood lipid profile in the postmenopausal obese women.

Objective: We aimed to investigate the effect of the differing amino acid (AA) release dynamics of two protein sources on the growth performance, nitrogen deposition, plasma biochemical parameters, and muscle synthesis and degradation of piglets when included in their diets at normal and low concentrations. Methods: Forty-eight piglets (Duroc×Landrace×Large White) with initial body weight of 7.45±0.58 kg were assigned to six groups and fed one of 6 diets. The 6 dietary treatments were arranged by 3×2 factorial with 3 protein sources and 2 dietary protein levels. They are NCAS (a normal protein content with casein), NBlend (a normal protein content with blend of casein and corn gluten meal), NCGM (a normal protein content with corn gluten meal), LCAS (a low protein content with casein), LBlend (a low protein content with blend of casein and corn gluten meal), LCGM (a low protein content with corn gluten meal). The release dynamics of AA in these diets were determined by in vitro digestion. The digestibility, utilization and biological value of nitrogen in piglets were determined by micro Kjeldahl method. Plasma insulin was measured by enzyme-linked immunosorbent assay kits. The protein expression of mediators of muscle synthesis and degradation was determined by western blotting. Results: Although the consumption of a low-protein diet supplemented with crystalline AA was associated with greater nitrogen digestion and utilization (p<0.05), the final body weight, growth performance, nitrogen deposition, and phosphorylation of ribosomal protein S6 kinase 1 and eIF4E binding protein 1 in the muscle of pigs in the low-protein diet-fed groups were lower than those of the normal-protein diet-fed groups (p<0.05) because of the absence of non-essential AA. Because of the more balanced release of AA, the casein (CAS) and Blend-fed groups showed superior growth performance, final body weight and nitrogen deposition, and lower expression of muscle ring finger 1 and muscle atrophy F-box than the CGM-fed groups (p<0.05). Conclusion: We conclude that the balanced release of AA from CAS containing diets and mixed diets could reduce muscle degradation, favor nitrogen retention, % intake and improve growth performance in pigs consuming either a normal- or low-protein diet.
